CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No.11/720,693, filed Jun. 1, 2007, pending; which is the national stage ofPCT Application No. PCT/EP2005/056609, filed 8 Dec. 2004, which claimspriority from European Patent Application No. 04106383.5, filed 8 Dec.2004, and U.S. Application No. 60/634228, filed 8 Dec. 2004, the entiredisclosures of which are hereby incorporated in their entirely.

The human genome encompasses some 2,000 proteins that utilize adenosine5′-triphosphate (ATP) in one way or another and some 500 of these encodefor protein kinases, i.e the protein-tyrosine andprotein-serine/threonine kinases, that share a catalytic domainconserved in sequence and structure but which are notably different inhow their catalysis is regulated. Substrate phosphorylation by theseenzymes is nature's predominant molecular way of organizing cellularsignal transduction and regulating biochemical processes in general. Itis not surprising, therefore, that abnormal phosphorylation of cellularproteins is a hallmark of disease and that there is a growing interestin the use of kinase inhibitors as drugs for therapeutic intervention inmany disease states such as cancer, diabetes, inflammation andarthritis.

It is an object of the present invention to provide such kinaseinhibitors, that are quinazoline derived macrocycles, hereinafter alsoreferred to as multi targeting kinase inhibitors (MTKI), found topossess anti-proliferative activity, such as anti-cancer activity andwhich are accordingly useful in methods of treatment of the human oranimal body, for example in the manufacture of medicaments for use inhyper proliferative disorders such as atherosclerosis, restenosis andcancer. The invention also relates to processes for the manufacture ofsaid quinazoline derivatives, to pharmaceutical compositions containingthem and to their use in the manufacture of medicaments of use in theproduction of anti-proliferative effect.

In particular, the compounds of the present invention were found toinhibit tyrosine kinase enzymes, also called tyrosine kinases. Tyrosinekinases are a class of enzymes, which catalyse the transfer of theterminal phosphate of adenosine triphosphate to the phenolichydroxy-group of a tyrosine residue present in the target protein. It isknown, that several oncogenes, involved in the transformation of a cellinto a malignant tumour cell, encode tyrosine kinase enzymes includingcertain growth factor receptors such as EGF, FGF, IGF-1R, IR, PDGF andVEGF. This family of receptor tyrosine kinases and in particular the EGFfamily of receptor tyrosine kinases are frequently present in commonhuman cancers such as breast cancer, non-small cell lung cancersincluding adenocarcinomas and squamous cell cancer of the lung, bladdercancer, oesophageal cancer, gastrointestinal cancer such as colon,rectal or stomach cancer, cancer of the prostate, leukaemia and ovarian,bronchial or pancreatic cancer, which are examples of cell proliferationdisorders.

Accordingly, it has been recognised that the selective inhibition oftyrosine kinases will be of value in the treatment of cell proliferationrelated disorders. Support for this view is provided by the developmentof Herceptin® (Trastuzumab) and Gleevec™ (imatinib mesylate) the firstexamples of target based cancer drugs. Herceptin® (Trastuzumab) istargeted against Her2/neu, a receptor tyrosine kinase found to beamplified up to 100-fold in about 30% of patients with invasive breastcancer. In clinical trials Herceptin® (Trastuzumab) proved to haveanti-tumour activity against breast cancer (Review by L. K. Shawer etal, “Smart Drugs: Tyrosine kinase inhibitors in cancer therapy”, 2002,Cancer Cell Vol. 1, 117), and accordingly provided the proof ofprinciple for therapy targeted to receptor tyrosine kinases. The secondexample, Gleevec™ (imatinib mesylate), is targeted against the abelsontyrosine kinase (BcR-Abl), a constitutively active cytoplasmic tyrosinekinase present in virtually all patients with chronic myelogenousleukaemia (CML) and 15% to 30% of adult patients with acutelymphoblastic leukaemia. In clinical trials Gleevec™ (imatinib mesylate)showed a spectacular efficacy with minimal side effects that led to anapproval within 3 months of submission. The speed of passage of thisagent through clinical trials and regulatory review has become a casestudy in rapid drug development (Drucker B. J. & Lydon N., “Lessonslearned from the development of an Abl tyrosine kinase inhibitor forchronic myelogenous leukaemia.”, 2000, J. Clin. Invest. 105, 3).

Further support is given by the demonstration that EGF receptor tyrosinekinase inhibitors, specifically attenuates the growth in athymic nudemice of transplanted carcinomas such as human mammary carcinoma or humansquamous cell carcinoma (Review by T. R. Burke Jr., Drugs of the Future,1992, 17, 119). As a consequence, to treat different cancers there hasbeen considerable interest in the development of drugs that target theEGFR receptor. For example, several antibodies that bind to theextra-cellular domain of EGFR are undergoing clinical trials, includingErbitux™ (also called C225, Cetuximab), which was developed by ImcloneSystems and is in Phase III clinical trials for the treatment of severalcancers. Also, several promising orally active drugs that are potent andrelatively specific inhibitors of the EGFR tyrosine kinase are now welladvanced in clinical trials. The AstraZeneca compound ZD1839, which isnow called IRESSA® and approved for the treatment of advancednon-small-cell lung cancer, and the OSI/Genentech/Roche compoundOSI-774, which is now called Tarceva™ (erlotinib), have shown markedefficacy against several cancers in human clinical trials (Morin M. J.,“From oncogene to drug: development of small molecule tyrosine kinaseinhibitors as anti-tumour and anti-angiogenic agents, 2000, Oncogene 19,6574).

In addition to the above, EGF receptor tyrosine kinases are shown to beimplicated in non-malignant proliferative disorders such as psoriasis(Elder et al., Science, 1989, 243; 811). It is therefore expected thatinhibitors of EGF type receptor tyrosine kinases will be useful in thetreatment of non-malignant diseases of excessive cellular proliferationsuch as psoriasis, benign prostatic hypertrophy, atherosclerosis andrestenosis.

It is disclosed in International Patent Application WO96/33980 and in J.Med. Chem, 2002, 45, 3865 that certain 4 anilino substituted quinazolinederivatives may be useful as inhibitors of tyrosine kinase and inparticular of the EGF type receptor tyrosine kinases. Unexpectedly itwas found that Quinazoline derivatives of the present formula (I) thatare different in structure show to have tyrosine kinase inhibitoryactivity.

It is accordingly an object of the present invention to provide furthertyrosine kinase inhibitors useful in the manufacture of medicaments inthe treatment of cell proliferative related disorders.

The mixture was stirredat this temperature until the reaction was essentially complete and wasthen filtered through a short pad of celite and concentrated to dryness.The residue was re-dissolved in EtOAc and was partitioned between EtOAcand water. The combined organic layers were concentrated under reducedpressure and the residue was treated with MP-TMT in acetonitrileovernight. It was then filtered, the resin was washed with acetonitrilefollowed by DCM and the filtrate was concentrated to afford 4.

Compound 4 and aqueous K₂CO₃ (sat.) in MeOH (1:1) were stirred at roomtemperature for 1 hour. The reaction mixture was concentrated underreduced pressure, the residue was re-dissolved in DCM and washed withwater. The organic phase was separated, dried (MgSO₄) and concentratedunder vaccuo.

One skilled in the art will recognize that atherapeutically effective amount of the EGFR inhibitors of the presentinvention is the amount sufficient to induce the growth inhibitoryeffect and that this amount varies inter alia, depending on the size,the type of the neoplasia, the concentration of the compound in thetherapeutic formulation, and the condition of the patient. Generally, anamount of EGFR inhibitor to be administered as a therapeutic agent fortreating cell proliferative disorder such as atherosclerosis, restenosisand cancer, will be determined on a case by case by an attendingphysician.

Generally, a suitable dose is one that results in a concentration of theEGFR inhibitor at the treatment site in the range of 0.5 nM to 200 μM,and more usually 5 nM to 10 μM. To obtain these treatmentconcentrations, a patient in need of treatment likely will beadministered between 0.01 mg/kg to 300 mg/kg body weight, in particularfrom 10 mg/kg to 100 mg/kg body weight. As noted above, the aboveamounts may vary on a case-by-case basis. In these methods of treatmentthe compounds according to the invention are preferably formulated priorto admission. As described herein below, suitable pharmaceuticalformulations are prepared by known procedures using well known andreadily available ingredients.

Due to their high degree of selectivity as EGFR inhibitors, thecompounds of formula (I) as defined above, are also useful to mark oridentify the kinase domain within the receptor tyrosine kinasereceptors. To this purpose, the compounds of the present invention canbe labelled, in particular by replacing, partially or completely, one ormore atoms in the molecule by their radioactive isotopes. Examples ofinteresting labelled compounds are those compounds having at least onehalo which is a radioactive isotope of iodine, bromine or fluorine; orthose compounds having at least one ¹¹C-atom or tritium atom.

One particular group consists of those compounds of formula (I) whereinR¹ is a radioactive halogen atom. In principle, any compound of formula(I) containing a halogen atom is prone for radiolabelling by replacingthe halogen atom by a suitable isotope. Suitable halogen radioisotopesto this purpose are radioactive iodides, e.g. ¹²²I, ¹²³I, ¹²⁵I, ¹³¹I;radioactive bromides, e.g. ⁷⁵Br, ⁷⁶Br, ⁷⁷Br and ⁸²Br, and radioactivefluorides, e.g. ¹⁸F. The introduction of a radioactive halogen atom canbe performed by a suitable exchange reaction or by using any one of theprocedures as described hereinabove to prepare halogen derivatives offormula (I).

Another interesting form of radiolabelling is by substituting a carbonatom by a ¹¹C-atom or the substitution of a hydrogen atom by a tritiumatom.

Hence, said radiolabelled compounds of formula (I) can be used in aprocess of specifically marking receptor sites in biological material.Said process comprises the steps of (a) radiolabelling a compound offormula (I), (b) administering this radiolabelled compound to biologicalmaterial and subsequently (c) detecting the emissions from theradiolabelled compound.

Alternatively the compounds are labeled with stable isotopes. In thisform of labeling the naturally abundant isotopes of hydrogen, carbon andnitrogen (¹H, ¹²C and ¹⁴N) are replaced with stable isotopes of theseelements (²H [deuterium], ¹³C and ¹⁵N, respectively). Labeling withstable isotopes is used for two principal purposes:

-   -   Incorporation of stable isotopes into proteins, carbohydrates        and nucleic acids facilitates their structural determination at        the atomic level.    -   Metabolic studies exploiting the increased mass of compounds        labeled with stable isotopes

The term biological material is meant to comprise every kind of materialwhich has a biological origin. More in particular this term refers totissue samples, plasma or body fluids but also to animals, speciallywarm-blooded animals, or parts of animals such as organs.

When used in in vivo assays, the radiolabelled compounds areadministered in an appropriate composition to an animal and the locationof said radiolabelled compounds is detected using imaging techniques,such as, for instance, Single Photon Emission Computerized Tomography(SPECT) or Positron Emission Tomography (PET) and the like. In thismanner the distribution to the particular receptor sites throughout thebody can be detected and organs containing said receptor sites can bevisualized by the imaging techniques mentioned hereinabove. This processof imaging an organ by administering a radiolabelled compound of formula(I) and detecting the emissions from the radioactive compound alsoconstitutes a part of the present invention.

In yet a further aspect, the present invention provides the use of thecompounds according to the invention in the manufacture of a medicamentfor treating any of the aforementioned cell proliferative disorders orindications.

The amount of a compound according to the present invention, alsoreferred to here as the active ingredient, which is required to achievea therapeutical effect will, of course, vary with the particularcompound, the route of administration, the age and condition of therecipient, and the particular disorder or disease being treated. Asuitable daily dose would be from 0.01 mg/kg to 300 mg/kg body weight,in particular from 10 mg/kg to 100 mg/kg body weight. A method oftreatment may also include administering the active ingredient on aregimen of between one and four intakes per day.

While it is possible for the active ingredient to be administered alone,it is preferable to present it as a pharmaceutical composition.Accordingly, the present invention further provides a pharmaceuticalcomposition comprising a compound according to the present invention,together with a pharmaceutically acceptable carrier or diluent. Thecarrier or diluent must be “acceptable” in the sense of being compatiblewith the other ingredients of the composition and not deleterious to therecipients thereof.

The pharmaceutical compositions of this invention may be prepared by anymethods well known in the art of pharmacy, for example, using methodssuch as those described in Gennaro et al. Remington's PharmaceuticalSciences (18^(th) ed., Mack Publishing Company, 1990, see especiallyPart 8: Pharmaceutical preparations and their Manufacture). Atherapeutically effective amount of the particular compound, in baseform or addition salt form, as the active ingredient is combined inintimate admixture with a pharmaceutically acceptable carrier, which maytake a wide variety of forms depending on the form of preparationdesired for administration. These pharmaceutical compositions aredesirably in unitary dosage form suitable, preferably, for systemicadministration such as oral, percutaneous or parenteral administration;or topical administration such as via inhalation, a nose spray, eyedrops or via a cream, gel, shampoo or the like. For example, inpreparing the compositions in oral dosage form, any of the usualpharmaceutical media may be employed, such as, for example, water,glycols, oils, alcohols and the like in the case of oral liquidpreparations such as suspensions, syrups, elixirs and solutions: orsolid carriers such as starches, sugars, kaolin, lubricants, binders,disintegrating agents and the like in the case of powders, pills,capsules and tablets. Because of their ease in administration, tabletsand capsules represent the most advantageous oral dosage unit form, inwhich case solid pharmaceutical carriers are obviously employed. Forparenteral compositions, the carrier will usually comprise sterilewater, at least in large part, though other ingredients, for example, toaid solubility, may be included. Injectable solutions, for example, maybe prepared in which the carrier comprises saline solution, glucosesolution or a mixture of saline and glucose solution. Injectablesuspensions may also be prepared in which case appropriate liquidcarriers, suspending agents and the like may be employed. In thecompositions suitable for percutaneous administration, the carrieroptionally comprises a penetration enhancing agent and/or a suitablewetting agent, optionally combined with suitable additives of any naturein minor proportions, which additives do not cause any significantdeleterious effects on the skin. Said additives may facilitate theadministration to the skin and/or may be helpful for preparing thedesired compositions. These compositions may be administered in variousways, e.g., as a transdermal patch, as a spot-on or as an ointment.

It is especially advantageous to formulate the aforementionedpharmaceutical compositions in dosage unit form for ease ofadministration and uniformity of dosage. Dosage unit form as used in thespecification and claims herein refers to physically discrete unitssuitable as unitary dosages, each unit containing a predeterminedquantity of active ingredient calculated to produce the desiredtherapeutic effect in association with the required pharmaceuticalcarrier. Examples of such dosage unit forms are tablets (includingscored or coated tablets), capsules, pills, powder packets, wafers,injectable solutions or suspensions, teaspoonfuls, tablespoonfuls andthe like, and segregated multiples thereof.

The in vitro inhibition of a panel of kinases was assessed using theglass-fiber filter technology as described by Davies, S. P. et al.,Biochem J. (2000), 351; p. 95-105.

In the glass-fiber filter technology the activity of the kinase ofinterest is measured using an appropriate substrate that is incubatedwith the aforementioned kinase protein in the presence of (³³P)radiolabeled ATP. (³³P) Phosporylation of the substrate is subsequentlymeasured as radioactivity bound on a glassfiber-filter.
